PLUMBING SYSTEM Application filed August 7, 1930. Serial No. 473,559.

This invention relates to plumbing systems, and has for its primaryobject to provide an improved waste and vent stack installationembodying novel means for efa fectively venting a plurality of fixturesand which may be wholly enclosed and concealed within the walls of thebuilding.

It is another object of the invention to provide means for connecting aplurality of fixtures arranged upon either side of the vent and wastestacks with the vent stack.

It is an additional object of the invention to provide vent stackconnections for the fixtures which enables the ordinary standard wastepipe sections and coupling means therebetween to be employed.

More particularly, in a practical embodiment of the invention, I providea connecting member between one of the vent stack sections and thebranch vent pipes connected with the fixtures in the form of a simplecasting which extends across the waste stack,- and is so constructed,that it will be. wholly contained within the vertical wall of thebuilding.

It is also another object of the invention to provide a venting unitembodying the said casting and a vent pipe for connection with thedischargereceiving connecting T in the waste stack and which may beeasily and quickly installed or assembled and connected with the ventstack, after the waste stack has been installed.

. With the above and other objects in view, the invention consists inthe improved plumbing system and in the form, construction and relativearrangement of the several parts thereof, as will be hereinafter morefully described, illustrated in the accompanying drawings, andsubsequently incorporated in the subjoined claims.

In the drawings, wherein I have illustrated several simple and practicalembodiments of my present improvements, and in which similar referencecharacters designate corresponding parts throughout the several views,

Figure 1 is a vertical section through two floors of a building, showingone installation of my improved plumbing'system;

Fig. 2 is an enlarged fragmentary elevation;

Fig. 3 is a horizontal sectional view taken on the line 33 of Fig. 2;

Fig. 4 is an enlarged elevation of the lower portion of the installationshown in Fig. 1 looking at right angles thereto;

Fig. 5 is a horizontal section taken on the line 55 of Fig. 4;

Fig. 6 is a View similar to Fig. showing a modified form of the device,and

Fig. 7 is a horizontal sectional view taken on the line 77 of Fig. 6.

Referring in detail to the drawings, 5 and 6 designate vertically spacedfloors of a building, the vertical waste and vent stacks indicatedgenerally at 7 and 8 respectively, extend through or are incorporatedwithin the vertical walls of the building, as indicated by the brokenlines at 9 in Figs. 3, 5 and 7 of the drawings. It is desirable, thatall parts of the installation shall be completely concealed so thatthere are no projections from either face of the building wall. Thewaste and vent stacks are each composed of standard length pipe sectionswhich are connected by the discharge re ceiving members 10 having aplurality of suitable connecting nipples shown at 11 and 12 for theconnection thereto of drain pipes extending from the lavatory, watercloset, bath tub, or other fixtures in the plane of the respectivefloors of the building. The members 10 may be generally of similar typeto that shown in Fig. 5 of my issued Patent No. 1,747,514, of February18, 1930, but it is to be particularly noted that the connecting nipples12 projecting laterally from opposite sides of the member 10 are locatedin horizontal alignment with each other. Vith these nipples, thedischarge pipe sections 13 are connected at one of their ends, whilewith the other ends thereof, drain pipes extending from the fixtures(not shown) are adapted to be coupled. The pipes l?) are provided withspaced hubs 14 for the connection of the lower ends of verticallyextending vent pipe sections 15, one of which may be provided with meansshown at 16 for the connection thereto of the drain pipe from a sink orother fixture. Horizontally extending pipe sections 17 are connectedwith the upper ends of the vent pipe sections 15.

One of the pipe sections 17 is adapted to be directly coupled -wi h onesection of the vent stack 8 as shown at 17.

For the purz se of conne ting the vent pipe section 17 on the oppos toside of the vertic l L and waste stacks with said vent s dCli section, Iprovide a hollow casting gt-ierally indicated 18 which in one form ofL16 invention may be in the form of a short cyl nder closely surroundingthe waste stack and providing an annular passage as indicated at 19,said ring at one side thereof ha a. connecting nipple indicated at 20with which the end of the horizontal vent pipe section 17 is adapted tobe connected. At the opposite side of the casting 18, said has a hollowlateral extension providing a chamber 21 in communication with theannular chamber 19. The upend of a supplementary vent pipe 22 is connced with this chamber, the lower end of said pipe 22 being directlyconnected with the discharge receiving member 15 between the waste andvent stack sections. The chamber 21 is also conn ted to the section of le vent pipe 8 oppos to the connecting ni 17 as indicated at 23.

The casting 18 may be readily assembled with the vent stack section, andrequires no other sugpor ng means than its connection with the sectionof the vent stack and the pipes 17 and All of the fixtures will thus beffectively vented through the connections between the vent stack sectionand the drain discharge pipes 13. The casting 18 is of simple form, andas seen in Fig. 3 of the dranings, enables all of the parts to beinstalled wi in the vertical building wall of standard thickness,thuseliminating unsightly projections from the surfaces of wall.

In Fig. 1 of the drawings, I have shown the venting connections forfixtures arranged at both the ht and left hand sides of the waste andvent stacks, those on the right hand side being connected through thenovel form of the casting 18. In the lower part of 1, I have shown theventing means only on the left hand side of the waste and Vent stacks,the connecting nipples 12 and 20 of the members 10 and 18, being closedby means of suitable plugs. By arranging the nipples 12 opposite eachother and the nipples 17 and 20 also in horizontal alignment, the sameassembly ofpipe sections 13, 15 and 17 may be used-at either the rightor left hand sides of the waste and vent stacks for venting similarfixtures. It will of course, be understood that if, only a singlefixture is to be taken care of on one side of the waste and vent stacks,for instance,

the left hand side at the top in Fig. 1, one of the vertical pipesections 15 may be omit-' ted.

The casting 18 for venting the fixtures on the lower floor 5 in Fig. 1and as shown in Figs. 4 and 5 of the drawings, is of somewhat differentform from the casting 18 above described. It may consist of a flattubular structure extending horizontally across one side of the wastestack and suitably connected at one end with the vent stack section, theother end thereof shown at 20 being connected to the horizontal ventpipe section 17. The auxiliary vent pipe section 22 is extendedtransversely of the building wall and at its upper end is suitablycoupled with the casting 18 as indicated at 25.

In Figs. 6 and 7 of the drawings, I show a slightly modifiedconstruction, in which the casting 18 is in the form of an elongatedloop embracing the waste stack and providing parallel passages 18 atopposite sides thereof connected at their ends with the vent stack. Oneor both of these spaced horizontal vent passages may be coupled with theupper end of the vent pipe section 22 as indicated at .25.

From the foregoing description considered in connection with theaccompanying drawings, the construction, manner of use and severaladvantages of .my present improvements will be clearly and fullyunderstood. It will be apparent that I have provided a simple andinexpensive means for connecting the various fixtures with the ventstack of a plumbing system which enables the expense incident to suchinstallations to be materially reduced, with an appreciable saving inthe time consumed in placing the various parts and making theconnections therebetween. In the construction shown in Fig. 5, the wastestack may be completely installed, and the casting 18 together with thepipe section 22 and the section of the vent stack 8 then applied inassembled relation to the waste stack as'a single unit, after which theconnections with the laterally extending pipes 13 and 17 are made. Mypresent construction avoids the relatively complicated castingsincorporated as parts of the waste stack heretofore employed foreifecting a proper venting of the fixtures.

I have disclosed herein a practical mechanical form of the several novelfeatures of my present disclosure. t will however, be readily understoodto those skilled in the art, that these features might also beincorporated in various other alternative structural forms, and Iaccordingly reserve the privilege of resorting to all such legitimatechanges therein as may be fairly embodied within the spirit and scope ofthe invention as claimed.
